6. As others have noted, the police don't actually prosecute

But you'd have to change what society wants and the structure of the police.

The structure of the police, by their nature an institution isolated from the rest of society. It's not uncommon sports teams have a similar sort of incestuous culture. It helps to breed a camaraderie that is necessary to put the larger organization in a position to succeed. But that often breeds into itself an exclusionary tactic. Whether it's a locker room culture, or just distrust of outsiders.

But society as a whole seems to want criminals to go away even if we don't always agree on who the right criminals are. Look at the response here to the woman who alleged she was attacked and lit on fire by three white guys. Most people I saw were outraged that the crime wasn't immediately labeled a hate crime. I didn't see all of those people apologize when it was discovered that she did it to herself. Wanting street justice quickly is human nature, but it's not pretty.

Also I don't think that a lot of the people who say that CEOs or Wall Street executives need to be arrested overestimate what is illegal by thinking about what maybe should be illegal. A lot of what was done was technically legal, just immoral by my standards.

If you want a police force and justice system as a whole that better represents the interests of people, work to elect better people to office at every level. They will create better laws and a better legal structure.

Also work to create civilian review boards of cops. They can't watch themselves. Cops fight against it, but I think it creates a better sense of accountability for cops if they know they have real oversight.
